I-N-BK7 (CDGM H-K9L)
Amalensi Ayisiyingi Efomu Elingcono Kakhulu

Kumalensi ayindilinga, ubude bokugxila obunikeziwe bungachazwa ngenhlanganisela engaphezu kweyodwa yerediya yangaphambili nangemuva yokugoba.Inhlanganisela ngayinye yamajika angaphezulu izophumela enanini elihlukile lokujikajika okubangelwa ilensi.Irediyasi yokugoba yendawo ngayinye yamalensi amafomu angcono kakhulu yakhelwe ukunciphisa ukujika okuyindilinga kanye nekhoma ekhiqizwa ilensi, iyenze ibe ngcono ukuze isetshenziswe kuma-conjugates angapheli.Le nqubo yenza lawa malensi abize kakhulu kunamalensi e-plano-convex noma ama-bi-convex, kodwa angabizi kakhulu kunomugqa wethu weprimiyamu wamalensi ase-aspheric apholishiwe e-CNC noma ama-achromats.

Njengoba amalensi elungiselelwe usayizi wendawo omncane, angakwazi ukufinyelela ukusebenza okukhawulelwe kwe-diffraction kumadayamitha amancane okufakwayo.Ukuze usebenze kahle kakhulu ekugxilweni kwezinhlelo zokusebenza, beka indawo engaphezulu enerediyasi emfushane yokugoba (okungukuthi, indawo egobile kakhulu) ibheke emthonjeni obolile.

I-Paralight Optics inikeza i-N-BK7 (CDGM H-K9L) amalensi ayindilinga eFomu Elingcono Kakhulu aklanyelwe ukunciphisa ukujika okuyindilinga kuyilapho esebenzisa indawo eyindilinga ukuze akhe ilensi.Ngokuvamile zisetshenziswa kuma-conjugates angapheli kuzinhlelo zokusebenza zamandla aphezulu lapho okuphindwe kabili kungeyona inketho.Amalensi ayatholakala angagqokile noma ama-antireflection (AR) ama-coatings afakwe kuzo zombili izindawo ukuze kuncishiswe ukukhanya okuvela endaweni ngayinye yelensi ukuze kuncishiswe inani lokukhanya elivela endaweni ngayinye yelensi.Lezi zinhlobonhlobo ze-AR zenzelwe uhla lwe-spectral luka-350 - 700 nm (VIS), 650 - 1050 nm (NIR), 1050 - 1700 nm (IR).Lokhu kunamathela kunciphisa kakhulu ukubonakala okuphezulu kwendawo engaphansi engaphansi kuka-0.5% endaweni ngayinye, kunikeze ukudluliswa okumaphakathi okuphezulu kulo lonke uhla lwe-AR lwenamathela.Hlola amagrafu alandelayo ukuze uthole izithenjwa zakho.
